I bought this vacuum, because in the past I have found Black and Decker makes very good products.  This vacuum is strong -- it picks up a lot of dirt and lasts for a long time when charged.  I gave a low rating, because I am disappointed that the side door is not latched, it just opens at any time, which then dumps the dirt all over.  I was recently emptying the dirt into the garbage and the door just fell off.  Now I have it attached with duct tape.  I was going to get it repaired, but with the pandemic, that won't be happening any time soon.
